fix: ensure CLI exits after command completion (#12906)

* fix: ensure CLI exits after command completion

The CLI process would hang indefinitely after commands like
`openclaw gateway restart` completed successfully.  Two root causes:

1. `runCli()` returned without calling `process.exit()` after
   `program.parseAsync()` resolved, and Commander.js does not
   force-exit the process.

2. `daemon-cli/register.ts` eagerly called `createDefaultDeps()`
   which imported all messaging-provider modules, creating persistent
   event-loop handles that prevented natural Node exit.

Changes:
- Add `flushAndExit()` helper that drains stdout/stderr before calling
  `process.exit()`, preventing truncated piped output in CI/scripts.
- Call `flushAndExit()` after both `tryRouteCli()` and
  `program.parseAsync()` resolve.
- Remove unnecessary `void createDefaultDeps()` from daemon-cli
  registration — daemon lifecycle commands never use messaging deps.
- Make `serveAcpGateway()` return a promise that resolves on
  intentional shutdown (SIGINT/SIGTERM), so `openclaw acp` blocks
  `parseAsync` for the bridge lifetime and exits cleanly on signal.
- Handle the returned promise in the standalone main-module entry
  point to avoid unhandled rejections.

 ### Fixes
 
+- CLI: lazily load outbound provider dependencies and remove forced success-path exits so commands terminate naturally without killing intentional long-running foreground actions. (#12906) Thanks @DrCrinkle.
 - Clawdock: avoid Zsh readonly variable collisions in helper scripts. (#15501) Thanks @nkelner.
 - Discord: route autoThread replies to existing threads instead of the root channel. (#8302) Thanks @gavinbmoore, @thewilloftheshadow.
 - Agents/Image tool: cap image-analysis completion `maxTokens` by model capability (`min(4096, model.maxTokens)`) to avoid over-limit provider failures while still preventing truncation. (#11770) Thanks @detecti1.
